For the Dough
• Unsalted Butter (1 cup) – Provides richness and moisture; ensure it’s softened for easy creaming.
• Brown Sugar (¾ cup) – Adds moisture and depth of flavor due to molasses content; can substitute with coconut sugar for a caramel-like flavor.
• Granulated Sugar (½ cup) – Sweetens the cookies and contributes to a crisp exterior; avoid replacing as each sugar plays a specific role in texture.
• Egg (1 large) + Egg Yolk (1 egg yolk) – The whole egg adds moisture; the yolk boosts richness and chewiness, so don’t skip it for best results.
• Vanilla Extract (2 tsp) – Enhances the overall flavor profile; use pure vanilla for optimal taste.
• All-Purpose Flour (2 ½ cups) – The main structure-making ingredient for cookies; sifting can create a lighter texture.
• Cornstarch (1 tbsp) – Helps achieve a soft, tender bite; skip for a denser cookie, but it’s recommended for the best texture.
• Baking Soda (1 tsp) – Provides lift and a softer crumb; do not replace with baking powder as it will change the texture.
• Salt (½ tsp) – Balances sweetness and enhances flavors; always use in cookie recipes for depth. -
For the Add-ins
• Semi-sweet Chocolate Chips (1 ½ cups) – Key feature for added sweetness and gooeyness; swap with dark or milk chocolate for different flavor profiles.
• Toasted Walnuts (1 cup, chopped) – Adds crunch and nuttiness; toasting enhances their flavor significantly, so don’t skip it.
• Optional: Flaky Sea Salt – Adds a sweet-and-salty contrast; sprinkle on top before baking for a gourmet touch.
These Thick & Chewy Chocolate Chip Walnut Cookies will surely be a hit in your kitchen, filling your home with heavenly aromas and leaving everyone wanting more!
Step‑by‑Step Instructions for Thick & Chewy Chocolate Chip Walnut Cookies
Step 1: Toast Walnuts
Preheat your oven to 350°F (175°C). Spread the chopped walnuts on a baking sheet in an even layer and toast them for 8-10 minutes, or until golden and fragrant, keeping a close eye to prevent burning. Once toasted, remove from the oven, let them cool for a few minutes, and set aside.
Step 2: Cream Butter & Sugars
In a large mixing bowl, combine the softened unsalted butter with brown sugar and granulated sugar. Using an electric mixer, beat on medium speed for 2-3 minutes, or until the mixture is light and fluffy. This step is crucial for achieving the rich, chewy texture of your Thick & Chewy Chocolate Chip Walnut Cookies.
Step 3: Add Eggs & Vanilla
Add one large egg and one egg yolk to the creamed butter and sugars, along with the vanilla extract. Continue to mix on medium speed until everything is well combined and smooth, about 1-2 minutes. The addition of the extra yolk is essential for the rich, chewy consistency you’ll love in these cookies.
Step 4: Mix Dry Ingredients
In a separate bowl, whisk together the all-purpose flour, cornstarch, baking soda, and salt. This ensures that the leavening agents are evenly distributed. Take care to mix the dry ingredients thoroughly before adding them to the wet mixture, as this will greatly affect the texture of your Thick & Chewy Chocolate Chip Walnut Cookies.
Step 5: Combine Mixtures
Gradually add the dry ingredients to the wet mixture, stirring gently with a spatula or wooden spoon until a soft dough forms. Be careful not to overmix; you want the ingredients just combined for that perfect chewy texture. This dough is the foundation of your delicious cookies!
Step 6: Incorporate Add-ins
Gently fold in the semi-sweet chocolate chips and the toasted walnuts with a spatula. Mix carefully until the chocolate and walnuts are evenly distributed throughout the cookie dough, ensuring each bite of your Thick & Chewy Chocolate Chip Walnut Cookies is packed with flavor and crunch.
Step 7: Chill Dough
Use a large cookie scoop to portion out the dough balls onto a tray lined with parchment paper. Once portioned, cover the tray with plastic wrap and chill the dough in the refrigerator for at least 30 minutes. Chilling helps the cookies hold their shape while baking, resulting in thick, chewy cookies.
Step 8: Preheat Oven
While the dough is chilling, preheat your oven to 350°F (175°C). Line two baking sheets with parchment paper, making sure to prepare everything for when the dough is ready. This step will ensure even baking and prevent the cookies from sticking, allowing you to enjoy the perfect Thick & Chewy Chocolate Chip Walnut Cookies.
Step 9: Bake Cookies
After chilling, place six cookie dough balls on each prepared baking sheet, allowing space between them for spreading. Bake in the preheated oven for 11-13 minutes, or until the edges are light golden brown and the centers look slightly underbaked. This slight underbaking creates that gooey center everyone loves.
Step 10: Cool & Serve
Remove the cookies from the oven and allow them to cool on the baking sheet for about 5 minutes. Then, carefully transfer them to a wire rack to cool completely. For the ultimate experience, serve your Thick & Chewy Chocolate Chip Walnut Cookies warm; the chocolate will be melty and irresistible!

Thick & Chewy Chocolate Chip Walnut Cookies Recipe FAQs
What type of walnuts should I use for these cookies?
I recommend using toasted walnuts for that extra flavor kick. Chop them coarsely and toast them in the oven at 350°F for 8-10 minutes until they’re golden brown and fragrant. This brings out their rich nutty taste, elevating your Thick & Chewy Chocolate Chip Walnut Cookies!
How do I store my cookies to keep them fresh?
For optimal freshness, store your cookies in an airtight container at room temperature. They will stay fresh for up to one week. If you want to keep them longer, consider refrigerating them. Just note that refrigerating can make them slightly firmer, but they’ll last the same time.
Can I freeze the cookie dough?
Absolutely! To freeze the dough, scoop out individual cookie balls and place them on a baking sheet lined with parchment paper. Freeze the balls until solid, then transfer them to a resealable freezer bag or container. They can be stored for up to 3 months. When you’re ready to bake, you can bake them straight from frozen; just add an extra minute or two to the baking time.
What should I do if my cookies spread too much during baking?
If your cookies spread too much, it may be due to the butter being too soft or the dough not being chilled long enough. To remedy this, try chilling the dough for a longer period before baking—up to an hour if needed. You can also opt to use slightly colder butter, but don’t let it get rock hard; that would make it difficult to cream properly.
Are there any dietary considerations for these cookies?
Yes! These Thick & Chewy Chocolate Chip Walnut Cookies contain gluten and dairy due to the flour and butter. If you’re baking for someone with allergies, consider using gluten-free flour blends and dairy-free butter alternatives. Additionally, you can make them nut-free by omitting walnuts altogether or substituting with seeds like pumpkin or sunflower seeds for crunch.
